ROTARY ENGINE.

Application filed July 14, 1914.

To all whom it may concern Be it known that I, HUGO HEINRICH, a subject of the King of Saxony, and residing at Zwickau, in the Kingdom of Saxony and German Empire, have invented certain new and useful Improvements in or Relating to Rotary Engines, of which the following is a specification.

My invention relates to rotary engines particularly to a rotary inclosed engine of the kind in which the rotary piston is driven about its axis by means of a fluid driving agent such as water, gases or the like.

The object of my invention is to provide an engine of this type in which the rotary driving or forcing member is rigidly connected with the axis of rotation vand arranged on the fixed cylinder. rEhe useful work propei| in this type of inclosed engine is performed solely in the interior of the rotating forcing member or between the latter and the fixed cylinder, so that the employment of any single or independent engine on the compound or the twin svstem is obviated.

My invention is a modification of the invention described and shown in my application Ser. No. 820816 filed February 25th 1914 and is shown in the accompanying drawings wherein:

Figure l is a longitudinal section of the engine constructed as a twin-engine and acting simultaneously as steam engine and as compressor. Fig. 2 is a vertical section through the steam engine. Fig. 3 is a vertical section through part of the compressor. Figs. f-fto 6 are sectional views of the controlling members which, instead of being arranged directly in the fixed cylinder as in Figs. l and 2, are housed in a special casing arranged axially in the wall of the fixed cylinder of the engine, whereby (as particularly shown in Fig. 4) the casing carrying the controlling members can be introduced and removed through an opening leading to the exterior.

The forcing member means that portion of the inclosed engine which, in cases in which it is employed as a steam engine, is displaced by the motive fluid (steam) relatively to the fixed cylinder, z'. e., is rotated eccentrically around the latter or in cases in which the inclosed engine is used as a pump, causes the Specification of Letters Patent.

medium to be conveyed (such as water or the like) from the inlet to the outlet.

The engine consists of the fixed inner cylinder 3 and the rotatable outer cylinder 2 eccentrically disposed relative to said inner cylinder and acting as the forcing member. The cylinder 2 is inclosed in a special casing 17 and is rigidly connected to the rotary shaft 9 by means of its parts l forming a hub. Upon the latter the blade 4 is mounted with its annular portion 4a so as to be guided co-axially with the forcing member 2 which rotates about the fixed cylinder 3. The free end of the blade 4 is guided in a recess 3a in the fixed cylinder 8 and extends to the inner periphery of the forcing member 2 against which the blade permanently bears so as to form a good joint during the rotation of the cylinder 2. The blade, which can be packed in the recess 3 of the fixed cylinder l by a special guide member 3b, divides the inclosed space in such a manner, that the motive fiuid to be admitted (such as liquids, gases, or the like), is kept separated from the fluid to be discharged. The annular portion 4 of the blade 4 moves entirely freely within the fixed cylinder 3 as it is no longer absolutely necessary that it should make a joint-tight Contact with the cylindrical inner wall of. this cylinder. From this it will be apparent that the inner wall of the fixed cylinder 3 need not be confined to the cylindrical form, but can be shaped in such a manner as to best suit the required conditions. This is illustrated in Figs. 2 and 3 where the superfious walls are indicated in broken lines.

In order to avoid making excessively large openings for the distributing ports l5 and 15a provided in the fixed cylinder 3 for the motive fiuid, the said openings are partly formed in the side wall forming the cover as shown in Figs. 2 and 3. Instead of the distributing ports l5 and 15a which are wholly or partly opened and closed by the rotating member 2, being arranged partly in the cylinder and partly in the cover, these ports can of course be arranged only in the cylinder or only in the cover, 5 and 5a are admission ports for the motive fluid while 16 and 16a are exhaust ports.

By suitably making the fixed cylinder 3 either alone or in conjunction with the cover elements hollow for the passage of a heating or cooling medium, the said cylinder can be utilized, in case of need, for heating and cooling purposes. Moreover, in order to completely balance the rotary masses, the rotary member 9. isV provided with a part 2l acting as a counterweight.

While in the construction of the inclosed engine illustrated in Figs. l to 3 the controlling members have been assumed to be directly inserted in the fixed cylinder 3, Figs. 4 to 6 illustrate the arrangement of the controlling members 20 in a common casing 2l fixed in the wall of the cylinder 3. T he casing 21 carrying the distributing and cut-olf members 9.0 is mounted in a bore provided in the wall of the fixed cylinder 3 and can be introduced and removed through an opening leading to the exterior as shown particularly in Fig. 4. According to Fig. l, in a casing composed of one part, two or more inclosed engines of the same size are arranged side by side on a common shaft 9. With such an arrangement the axial pressure arising in one engine is balanced by the axial pressure in the other engine.

The engine can be used either as a prime mover, or as a pump. The arrangement of the controlling members regulating the admission and the discharge of the motive fluid depends upon the special purpose which the engine is to serve. When the engine is used as a motor, the exhaust members are unnecessary, while when it is used as a pump, compressor or the like the admission members are unnecessary. The motive fluid passes through the admission ports 5 and 5a, flows through the port 6 provided in the fixed cylinder 3 till it reaches discharge controlling member 20 provided in this cylinder and proceeds through this member and the port 15L into the work chamber 14 located between the fixed cylinder 3 and the forcing members 2. Here, according to whether the engine is operated as a steam engine or as a pump, the forcing member 2 is caused to rotate with its shaft 9 by the action of the motive fluid (steam) the latter passing through the port l5 to the discharge port 16; or else the motive fluid (water or the like) is forced by the rotary forcing member 2 from the inlet A5a to the outlet 16a. As the blade 4 moves it forms a good joint along the side wall of the cylinder', while its free end constantly is in close contact with the inner periphery of the forcing member 2, thus dividing the inclosed space in such a manner that the motive fluid to be admitted remains separated from the medium to be discharged.

What I claim is:

l. A rotary engine, comprising a Xed cylinder, a rotary shaft, a forcing member mounted on said shaft and adapted to rotate eccentrically about the said cylinder, and a blade arranged to be guided coaxially with the said forcing member.

2. A rotary engine comprising a fixed hollow cylinder adapted to receive a heating or cooling medium, a rotary shaft, a forcing member mounted on said shaft and adapted to rotate eccentrically about the said cylinder, and a blade arranged to be guided co-axially with the said forcing member.

3. A rotary engine comprising a fixed cylinder, a rotary shaft, a forcing member mounted on said shaft, a blade arranged to be guided co-axially with the said forcing member, cut-off members and a casing for the reception of said cut-off members, built into the wall of said cylinder.

4. A. rotary engine comprising a fixed cylinder, a rotary shaft, a forcing member mounted on said shaft, a blade arranged to be guided co-axially with the said forcing member, cut-ofi" members, a casing for the reception of said cut-off members, and an opening in the wall of the said cylinder leading to the exterior for the reception of the said casing.

5. A rotary engine comprising a fixed cylinder, a ,rotary shaft, a forcing member mounted on said shaft, a blade arranged to be guided co-axially with the said forcing member, cut-olf members, a casing for the reception of said cut-off members, and a bore arranged axially in the wall of the said cylinder for the reception of the said casing.

A. rotary engine comprising two fixed cylinders arranged side by side, a rotary shaft, tivo forcing members one for each cylinder mounted on said shaft and adapted to rotate eccentrically about the said cylinders, blades arranged to be guided co-axially with the said forcing members, and a single casing inclo'sing all the parts.

In testimony whereof I have aflixed my signature in presence of two witnesses.
